Vim when I can, and when I can't, Neovim with plugins (LazyVim). Both are fast. I have had troubles with Neovim and configuration, and it does some things that really annoy me (like autoclosing parentheses - it just messes up everything). Honestly, the only feature that I really need is Go To Definition.

But vim - I absolutely love it. I started using it nearly 20 years ago and it still does everything one could want if you're willing to learn the keymaps and commands. Macros, ci), block indentation and so on. It's even great for editing XML. If the codebases I'm working on these days weren't so large and complicated, I would still be using it with very little configuration in my .vimrc.
